Let the body cover a distance ‘a’ in time t 1, then a distance b in time t 2, c in time t 3 and so on, then the average speed of the body is found out by the following ratio:Īverage speed = (a + b + c + …)/ (t 1 + t 2 + t 3 + …). In this case when a body has different speed during different parts of the journey, we define the average speed as:Īverage Speed = (Total distance covered throughout the journey)/(Total time taken for the journey) If the distance between any two stations is 6km, what is the speed of the train?Īnswer: Here you can’t use the formula directly because as you may have observed the train has a different speed from A to B than from B to C. But what if there is an object that covers part of its journey with one speed and the other part with another speed? Let us say a train goes from station A to B in 2 minutes and from B to C in 3 minutes.

If ‘D’ is the distance traveled in some time ‘T’ then the speed of the object for this journey or ‘s’ is equal to s = D/T. The speed of an object is found out by dividing the distance that the object covers by the time in which the object takes to cover this distance.
